DNA Structure and Replication Which of the following is used to determine the appropriate stringency (Wallace rule)? Tm = 4 x (No.of A:T base pair) + 2 x (No.of G:C base pair) Tm = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) Tm = 69.3° + 0.41 (%)G+C -650/1 Tm = 4 x (No.of G:C base pair) + 2 x (No.of A:T base pair) Tm = 4 x (No.of A:T base pair) + 2 x (No.of G:C base pair) Tm = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) Tm = 69.3° + 0.41 (%)G+C -650/1 Tm = 4 x (No.of G:C base pair) + 2 x (No.of A:T base pair) ANSWER DOWNLOAD EXAMIANS APP
DNA Structure and Replication In a typical electrophoresis experiment, larger fragments of DNA move more slowly, so they appear nearer the top of a gel photograph slowly, so they appear nearer the bottom of a gel photograph quickly, so they appear nearer the top of a gel photograph quickly, so they appear nearer the bottom of a gel photograph slowly, so they appear nearer the top of a gel photograph slowly, so they appear nearer the bottom of a gel photograph quickly, so they appear nearer the top of a gel photograph quickly, so they appear nearer the bottom of a gel photograph ANSWER DOWNLOAD EXAMIANS APP
